The mold design is simplified, the development quantity of the mold is reduced, the material consumption is reduced, the light weight is realized, and the cost is reduced; the stress concentration at the section is optimized, and the installation is convenient and attractive.
Description
Technical Field
The utility model belongs to the technical field of heavy trucks, and relates to a rear suspension of a power assembly of a heavy truck.
Background
In the existing power assembly rear suspension structure (shown in figure 1), 1 bolt hole is connected with a frame girder, and 4 bolt holes are connected with a power assembly.
Defects of the background art:
the stress at the broken section is concentrated during the operation of the heavy truck, so that the heavy truck is easy to break and damage; the mold design is complex, the development cost is high, the left and right suspensions are different, and the left and right molds need to be developed, so that the cost is increased; no heavy material, high cost, inconvenient installation and beautiful appearance.
Disclosure of Invention
The utility model aims to provide a rear suspension of a power assembly of a heavy truck. Adopts a symmetrical structure, optimizes the appearance and the installation; the weight reducing holes are formed, the length and the height of the reinforcing rib plates are reduced, the weight is reduced, the modulus of opening is reduced, and the cost is reduced.
The technical scheme of the utility model is as follows: a rear powertrain mount for a heavy truck comprising a floor; the shape of the bottom plate is a T-shaped structure, which comprises a vertical plate and a horizontal plate: the vertical plate comprises a large bolt hole for connecting the power assembly; the horizontal plate comprises small bolt holes which are arranged on the upper side and the lower side of the bottom plate and are used for connecting frame girders; the bottom plate is provided with reinforcing rib plates, the reinforcing rib plates are two rows of double rib plates positioned at the upper and lower positions of the vertical plate of the bottom plate, and each rib plate in each row is arranged at the left and right sides of the central line in the upper and lower direction of the bottom plate; the lightening holes are arranged on the upper side and the lower side of the symmetry axis in the horizontal direction of the bottom plate, namely on the upper horizontal plate and the lower horizontal plate of the vertical plate.
Further, the boundary of the bottom plate is a round angle, and the vertical plate does not protrude from the left and right boundaries of the horizontal plate.
Further, the reinforcing rib plate is connected with the vertical plate and the horizontal plate of the bottom plate.
The utility model has the technical effects that: the length and the height of the reinforcing rib plate are reduced, the weight is reduced, the modulus of opening is reduced, and the cost is reduced.
The key of the utility model is to simplify the design of the mould, reduce the development quantity of the mould, reduce the material consumption to realize light weight and reduce the cost; the stress concentration at the section is optimized, and the installation is convenient and attractive.

Detailed Description
The whole scheme is symmetrical and the stress is even. In order to optimize the structure, the position of the reinforcing rib plate 2 is changed from a single rib plate to a double rib plate, which is symmetric in length left and right, and the total length and the total height are reduced; the overall dimension of the support bottom plate 3 is optimized, the structure is changed into vertical symmetry, the boundary is smooth, the protruding part is removed, and the stress concentration is reduced; in order to reduce the cost, the weight-reducing holes 5 are provided in the suspension to reduce the weight of the vehicle when the strength requirement is satisfied.
The rear suspension of a power train of a heavy truck mainly comprises a floor 3.
The boundary of the bottom plate 3 is a round angle, and the vertical plate does not protrude from the left and right boundaries of the horizontal plate.
The shape of the bottom plate 3 is a T-shaped structure comprising a vertical plate and a horizontal plate: the vertical plate comprises bolt holes 4 for connecting the power assembly. The horizontal plate comprises bolt holes 1 which are arranged on the upper side and the lower side of the bottom plate 3 and are used for connecting frame girders.
The reinforcing rib plates 2 are vertical plates and are arranged on the left side and the right side of the central line of the bottom plate 3 in the up-down direction.
The lightening holes 5 are arranged on both sides of the horizontal symmetry axis of the bottom plate 3, namely on the upper and lower horizontal plates of the vertical plate.
Claims (3)
